Waste water proportioner 500 in the present embodiment mainly realizes its Automated condtrol by motor, specifically by fixation
Motor 3 in waste water ratio main body 1 come realize adjust shaft core 2 motion, adjust shaft core 2 adjustable side 23 arrange limited location
Tooth 230, is connected with the travelling gear 4 engaged with the limiting tooth 230 of adjustable side 23 on the motor shaft of motor 3, motor 3 drives transmission
4 rotating of gear, the driving cog on travelling gear 4 are engaged with the limiting tooth 230 in shaft core 2 is adjusted, and realize similar worm and gear
Transmission, so as to realize adjusting the advance or retrogressing of shaft core 2.Motor 3 in the present embodiment adopts small synchronous motor, miniature synchronization
Motor is rotation compared with slow type, is capable of achieving its rotating, has larger torque, is indicating that machine quits work or machine power down every time
When, then motor 3 realizes reversion, allows waste water ratio to be adjusted to minimum, that is, allows waste water ratio to be zeroed, so as to realize its accurate control, and not
The situation such as get muddled occurs.
Wherein motor realizes its Based Intelligent Control by controller, and controller is connected with motor 3, and one is connected with controller
Microswitch 7, adjusts shaft core 2 and is provided with for stirring the plectrum 24 of microswitch 7, break-make of the controller according to microswitch 7
Carry out controlled motor 3 to operate, so as to when regulation shaft core 2 moves to certain position, plectrum 24 stirs microswitch 7, microswitch 7
Make-and-break signal is exported to controller, feedback regulation shaft core 2 is moved in place, controller can stop according to the signal control motor 3
Running so that adjust 2 para-position of shaft core accurately, reaction concentrated water flow is solid.
In the present embodiment, current limliting end 22 is provided with the current limliting sealing ring 223 of 5 metering holes 222 and 6 equidistantly distributeds, limit
Stream sealing ring 223 is distributed in 222 both sides of metering hole, by the setting of current limliting sealing ring 223, flow-control can be caused more smart
Really.5 222 self-limiting ends of metering hole, 22 end is divided into hole one, hole two, hole three, Kong Si and hole five, its mesopore one to Kong Si
Aperture be gradually reduced, the aperture of the aperture in hole five more than Kong Si, four equidistantly distributed of Kong Yizhi holes, between Kong Siyu holes five
Spacing is equal to the twice of spacing between Kong Yiyu holes two, and the center between Kong Siyu holes five is considered as blind spot, blind spot position
For waste water ratio be in close stance, waste water ratio not water outlet, now all sealing rings function both on.When end and the exocoel at current limliting end 22
When room 13 connects, i.e. exocoel indoor water is directly entered centre bore 221 without metering hole 222, then flows into inner cavity chamber from five holes
12, throttling action is not now played, waste water proportioner 500 is rinse mode, equivalent to waste water full-gear, is capable of achieving reverse osmosis membrane
Used by flushing state, now current limliting sealing ring 223 cuts little ice；When Kong Yiwei metering holes, the water in exocoel room is from hole
One enters such as centre bore, the water after throttling can flow to inner cavity chamber 12 from Kong Erzhi holes five through centre bore, and centre bore 221 is used as one
Small-sized excessive structural, just plays the structure of noise reduction, reduces the noise produced because of strong injection so as to play；In the same manner, when outer
When the hole different from other of chamber 13 connects, the waste water proportioner 500 is in different gears, so as to realize that adjusting shaft core 2 changes
Become the effect of waste water specific discharge.
Concrete throttling gear control can be such as following table：
| Gear | Throttle orifice | Apopore | Miniature microswitch |
| One grade | Without throttle orifice | Kong Yi, hole two, hole three, Kong Si, hole five | Disconnected (record 1) |
| Two grades | Kong Yi | Hole two, hole three, Kong Si, hole five | Disconnected (record 2) |
| Third gear | Hole two | Hole three, Kong Si, hole five | Disconnected (record 3) |
| Fourth gear | Hole three | Kong Si, hole five | Disconnected (record 4) |
| Five grades | Kong Si | Hole five | Disconnected (record 5) |
| Six grades | Blind spot | Without apopore | Disconnected (record 6) |
In the present embodiment by taking 600G water purification machines as an example, correlative measurement is with GB/T 30307-2013 GB test conditions, water temperature 25
DEG C, as a example by test data during intake pressure 0.2MPa.
Following status data can be obtained：
For waste water proportioner a on condensed water outlet pipe 300 and play backflow effect condensed water return duct 400 on giving up
Water proportioner b, in machine system, has following 5 kinds pure discharge of wastewater states, wherein:The flow value of waste water proportioner a be
Test value under 0.7MPa, the flow value of waste water proportioner b are the test values under 0.4MPa：
| Waste water ratio a gears | Six grades | Five grades | Fourth gear | Third gear | Two grades | One grade |
| Waste water ratio a | 0 | 400 | 500 | 800 | 1000 | Standard-sized sheet (flushing state) |
| Waste water ratio b gears | One grade | Two grades | Third gear | Fourth gear | Five grades | Five grades |
| Waste water ratio b | 2500 | 2000 | 1500 | 1000 | 500 | Nothing |
Test result is as follows：
(1) (1 is flowed out without concentrated water:0), i.e. 0 waste water, flows out without condensed water, infinite reflux, only starts shooting or rinses one when closing water
Fix time, have flushing water to flow out in certain hour, this is that, without waste water water conservation mode, only a small amount of flushing water flows out, and now TDS is visited
The raw water TDS value scope for surveying the monitoring of device 105 is 0 21, and some areas water quality is preferable or part uses barreled in order to meet for this shelves
The family of office of water, the situation that waste water can be avoided excessive, now waste water proportioner a gear is six grades, and flow is 0, waste water
Proportioner b gears are one grade；
(2) when raw water TDS value scope is 22 100, pure waste water ratio is set to 4：1；Now waste water proportioner a gear is five
Shelves, flow is 400, and waste water proportioner b gear is two grades, and backflow ratio type is 2000；
(3) when raw water TDS value scope is 200 300, pure waste water ratio is set to 3：1；Now waste water proportioner 500a gear
For fourth gear, flow is 500, and waste water proportioner b gear is third gear, and reflux ratio offset is 1500；
(4) when raw water TDS value scope is 301 400, pure waste water ratio is set to 2：1；Waste water proportioner 500a gear is four
Grade, flow is:800, waste water proportioner b gear is third gear, and reflux ratio offset is 1000；
(5) when raw water TDS value scope is 400 600, pure waste water ratio is set to 1：1；Waste water proportioner 500a gear is four
Grade, flow is:1000, waste water proportioner b gear is third gear, and reflux ratio offset is:500；
(6) higher TDS then alarms, report to the police：1 continues controlling the water circulation, when raw water TDS>1000, then cannot
Use.
Concrete reflux ratio can be matched with reference to pressure condition before reverse osmosis membrane correlated performance and film, waste water ratio of then shaping
Device b correlation gear flow values, to obtain the water quality of optimum, in explanation, unit is only used as reference, such as following table statistical data：
This technology can increase backflow Intelligent adjustment flow, by above-mentioned technical side by Intelligent adjustment wastewater flow size
Case, the water saving of maximum efficiency ground.So that the water purifier farthest can be economized on water where water quality is preferable, while being capable of basis
Various environment, the pure waste water ratio of Intelligent adjustment produce water ratio hook with pure water water quality quality, have overturned the phase of early stage water purifier
Thinking is closed, is increased pure water flow to greatest extent, and is got more preferable pure water water quality.
In a word, presently preferred embodiments of the present invention, all equalizations made according to scope of the present invention patent be the foregoing is only
Change and modification, should all belong to the covering scope of patent of the present invention.
